Abstract

Nanosilver of nanometer-sized silver (Ag+) particles (2-5 nm diam) are used in various applications as an anti-microbial. Boric acid (H3BO3) is water soluble (pH=7). Boric acid is ethylene synthese inhibitor and reduce ethylene production through reducing the ACC synthase and ACC oxidase delays senescence of flower. In this study of different concentrations of boric acid and nano-silver was evaluated and vase life, fresh weight loss, flower opening index and the number of bacteria in preservative solution were measured. The highest cut rose flower ‘Yellow Island’ longevity was obtained in pulse-treated flowers with 100 mg l-1 boric acid (4 days).
